Description

Technical Field

[0001] This utility model belongs to the technical field of cleaning towel structure, and specifically refers to a towel. Background Technology

[0002] As people's living standards continue to improve, their demands for daily necessities are also increasing. Textiles are indispensable in people's daily lives, such as towels. Towels can be used for washing the face, drying hands, drying hair, and also for cleaning windows and windowsills. They have a wide range of uses in daily life, and users often need to choose fabrics with special materials for specific purposes.

[0003] For example, Chinese patent CN202020627039.7, concerning a yarn, fabric, and facial cleansing towel for terry cloth textiles, mainly relates to the field of yarn, fabric, and facial cleansing towel for terry cloth textiles. This product enhances absorbency by weaving a highly absorbent combed cotton sliver with a PVA cotton sliver, effectively improving the user experience. However, this product also has some shortcomings: the PVA content is not high enough, resulting in insufficient absorbency; and there is no significant difference in cleaning effect between the two sides, failing to provide a variety of cleaning scenarios. Summary of the Invention

[0004] The purpose of this invention is to provide a towel with good water absorption that has different wiping effects on both sides.

[0005] The purpose of this utility model is achieved as follows:

[0006] A towel includes a mesh-structured fabric with mesh openings. Polyvinyl alcohol formaldehyde (PVA) can penetrate into the mesh openings of the fabric fibers, and the PVA is tightly bonded to the fabric to form a whole. The fabric is located inside the PVA, and the PVA thickness is different on both sides of the fabric. In a dry state, the surface roughness of the thicker side is greater than that of the thinner side. In a wet state, the surface friction of the thicker side is greater than that of the thinner side.

[0007] Furthermore, polyvinyl formal is white in its dry state.

[0008] Furthermore, polyvinyl formal does not completely fill the mesh; both the thicker and thinner sides of the surface form pits with the mesh as their shape.

[0009] Furthermore, polyvinyl alcohol formaldehyde completely fills the mesh, with irregular pits on the thicker side and pits formed by the mesh on the thinner side.

[0010] Furthermore, the fabric is a fiber fabric composed of microfibers. The microfibers have many micropores between the microfibers, forming a capillary structure. The capillary structure can adsorb polyvinyl alcohol formaldehyde and form a whole.

[0011] Furthermore, the thicker side of the polyvinyl alcohol formaldehyde is spread all over the surface of the fiber fabric, and the fiber fabric is not exposed; the thinner side of the polyvinyl alcohol formaldehyde is spread thinly on the surface of the fiber fabric, and part of the fiber fabric is exposed.

[0012] Furthermore, polyvinyl alcohol formaldehyde is bonded to the fiber fabric by hot melting. The hot-melted polyvinyl alcohol formaldehyde can be laid on the surface of the fiber fabric and enter the pores of the fiber fabric; after cooling, the cleaned cloth forms a complete whole.

[0013] Furthermore, the surfaces on both sides of the towel are flat.

[0014] Furthermore, each square meter of towel contains 60-150 grams of polyvinyl alcohol formaldehyde.

[0015] Furthermore, the thickness of the thicker polyvinyl formal is at least 1.5 times that of the thinner polyvinyl formal.

[0016] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0017] 1. This invention utilizes polyvinyl alcohol formaldehyde (PVA) as the main material. PVA penetrates into the pores of the fabric and the mesh between the fibers, forming a complete unit. During use, PVA exerts its strong adsorption capacity for better cleaning. Furthermore, by applying different thicknesses of PVA to both sides of the fabric, the towel achieves different cleaning effects on each side. Since PVA hardens after drying, the more PVA present, the rougher it becomes after hardening. The different roughness on both sides of the towel allows the user to choose the more suitable side for cleaning. Similarly, when PVA is wet, the more PVA present, the greater the friction. The different friction on both sides of the towel also allows the user to choose the more suitable side for cleaning.

[0018] 2. This utility model incorporates polyvinyl formal in at least two different ways: Method 1: The polyvinyl formal does not completely fill the mesh; both the thicker and thinner sides of the surface form recesses shaped like the mesh. Method 2: The polyvinyl formal completely fills the mesh; the thicker side has irregular recesses, and the thinner side has recesses shaped like the mesh. The fundamental purpose of the towels formed by these methods is to create a surface that is not completely flat, with recesses. The purpose of these recesses is to increase the contact area of ​​the polyvinyl formal, allowing it to absorb water quickly and improving its absorbency. Furthermore, the polyvinyl formal softens rapidly after absorbing water, enhancing the user experience.

[0019] 3. In this invention, the thicker side of the polyvinyl alcohol formal is fully covered on the surface of the fiber fabric, with no exposed fiber fabric; the thinner side of the polyvinyl alcohol formal is thinly covered on the surface of the fiber fabric, with some fiber fabric exposed. With this structural design, during cleaning, the thicker side is completely in contact with the surface of the item being cleaned by the polyvinyl alcohol formal, resulting in high friction when dry and high resistance when wet; the thinner side has low friction when dry and low resistance when wet. Furthermore, the thinner side has some exposed fiber fabric, which, by utilizing the low resistance of the fiber fabric, reduces the frictional resistance on the thinner side.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Figure 1-8 As shown:

[0030] A towel includes a mesh-structured fabric with internal mesh openings. Polyvinyl alcohol formaldehyde (PVA) 1 can penetrate into the mesh openings of a fiber fabric 2. The PVA and fabric are tightly bonded together to form a whole. The fabric is located inside the PVA, and the thickness of the PVA on both sides of the fabric differs. Figure 2 and Figure 4 As shown, the thickness of the thinner polyvinyl alcohol (PVA) layer is L1, and the thickness of the thicker layer is L2. In a dry state, the surface roughness of the thicker side is greater than that of the thinner side; in a wet state, the surface friction of the thicker side is greater than that of the thinner side. PVA has strong water absorption and, as a surface layer, can better absorb stains. This towel has many uses, such as for daily face washing and body wiping. It can quickly absorb liquid from the body surface, and the different friction on both sides is effective for wiping away dirt. It can also be used to dry hair by rubbing it against the hair. Another use is for cleaning glass or tabletops. When the towel is wet, the friction can remove stubborn dirt from the surface. The different friction on both sides allows users to choose different surfaces for different types of dirt, especially for cleaning dirty glass, where the thicker side can be used first, followed by the thinner side. The difference in roughness between the two sides of a towel can be caused by several factors: Polyvinyl alcohol formaldehyde (PVA) loses water and hardens when dry, becoming rough after natural drying, so the thicker the surface, the rougher it will appear; another factor is the manufacturing process. When a towel is placed in a mold made of PVA foam, the side of the towel that is in contact with the mold surface will be smoother, while the exposed side will be rougher.

[0031] Polyvinyl alcohol formaldehyde (PVA) is white when dry. This white color is used by users to distinguish the thicker side of the towel, which has significantly more white than the thinner side. Users can differentiate the thicker and thinner sides based on the surface color and roughness; the rougher side is the thicker side. Furthermore, this color serves as an indication to the user that if the white color is not obvious or turns black when dry, the towel should be replaced.

[0032] The fabric is fiber fabric 2, which is composed of microfibers. The fiber fabric can be entirely composed of microfibers, or it can be a mixture of some ordinary fibers and some microfibers. The specific composition is determined by the manufacturer's actual production process, but the fiber fabric must contain microfibers. Microfibers have many tiny pores between the microfibers, forming a capillary structure. This capillary structure can adsorb polyvinyl alcohol (PVA) formal and form a whole. Microfibers and PVA formal have a stronger binding affinity; PVA formal can be effectively adsorbed on the surface and within the pores of the fiber fabric, resulting in a stronger overall integrity of the PVA formal and the fiber fabric. Preferably, PVA formal is connected to the fiber fabric by heat fusion. The heat-fused PVA formal can be laid on the surface of the fiber fabric and enter the pores of the fiber fabric; after cooling, the cleaned fabric forms a complete whole.

[0033] The towel has smooth surfaces on both sides. This smoothness refers to the towel's entire surface being flat; in reality, the smooth surface of a towel has numerous tiny pits. During the towel-making process, there is a rolling process that achieves this smooth surface.

[0034] Each square meter of towel contains 60-150 grams of polyvinyl alcohol formaldehyde. The amount of polyvinyl alcohol formaldehyde added varies depending on the thickness of the towel, and this amount is determined by the manufacturer.

[0035] The thickness of the thicker polyvinyl formal is at least 1.5 times that of the thinner polyvinyl formal.

[0036] Example 1: As Figure 5 and Figure 6 As shown, polyvinyl formal does not completely fill the mesh; both the thicker and thinner sides of the surface form pits with the mesh as their shape.

[0037] The thicker side, polyvinyl alcohol formaldehyde 1b, covers the entire surface of the fiber fabric, leaving the fiber fabric uncovered. During cleaning, the polyvinyl alcohol formaldehyde is in complete contact with the surface of the object being cleaned, resulting in strong water absorption, high friction, and powerful cleaning. The thinner side, polyvinyl alcohol formaldehyde 1a, covers the surface of the fiber fabric, leaving some fiber fabric exposed. This fiber fabric is lightweight and soft, and both the fiber fabric and the polyvinyl alcohol formaldehyde on this side are in contact with the surface of the object being cleaned, resulting in strong water absorption, moderate friction, and moderate cleaning.

[0038] Implementation 2: such as Figure 7 and Figure 8 As shown, the difference between the two lies in the thickness of the polyvinyl formal. The polyvinyl formal completely fills the mesh, with irregular pits on the thicker side and pits formed by the mesh on the thinner side.

[0039] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
